You're
misusing the term "close-mindedness"....I haven't read the book, but have read several excerpts, along with many reviews: the book is a bit more on the fictional paradigm of things, but that doesn't diminish it's value. There are concepts that don't seem to have a logical underlining cause, like many reality checks, and they do indeed work. So advocating for "close-minded" or neurology (you know neurology refers to disorders right :P? You probably mean neuroscience) for saying someone will probably not like the book....Besides, I think certain lucid dreaming books are very useful in a sort of "inspiration" perspective.
That goes along with Robert Wagner's book (Gateway to Inner Self): a less "scientific" kind of book, but nonetheless an excellent read, and this opinion is from a "close-minded" onironaut :P
